A cup of tea is initially at a temperature of 85∘C 85^{\(\circ\)}\(\text{C}\) and cools in a room maintained at 20∘C 20^{\(\circ\)}\(\text{C}\) . If the cooling constant is k=0.03 k = 0.03 min−1\(\text{min}\)^{-1}, after how many minutes will the tea reach 40∘C 40^{\(\circ\)}\(\text{C}\) ? Round your answer to the nearest whole number.
